nonlinear acoustics

Nonlinear acoustics studies sound waves when they behave in ways that aren't proportional to their intensity. In simple terms, when sound waves are very strong, they can create new frequencies and patterns instead of just amplifying existing ones. This phenomenon occurs in various contexts, such as in musical instruments, medical imaging, and noise control. It helps us understand complex sound behaviors and leads to advancements in technology and therapies, enhancing everything from ultrasound applications to audio quality in music and communication.
